The displays
Remove the cover of the display enclosure and it should be on the back of the faceplate.
No, you cannot.
The battery in the 808-P2 Special lasts between 8 to 10 years under normal operation.
The battery in the 810X sender bar lasts between 8 to 10 years under normal operation.
The batteries in the 810-PS2 ProSeries last about 3 years. The nighttime LEDs will lower the lifetime of the batteries.
SeeLeveL Special 808-P2 – No. The battery is non-serviceable. Please return it to Garnet for replacement.
SeeLeveL ProSeries 810-PS2 – Yes. Replace with four new AA cell batteries.
SeeLeveL Truck Programmer 817-USB – Yes. The 817-USB operates on four user replaceable “AA” batteries
The display should never read zero due to the height of the anchor support plate recommended at 3” from the bottom of the tank. The level is read at the midway point of the float therefore even with no anchor support it cannot read zero.
Yes. To recalibrate the display you will need to use a SeeLeveL Truck Programmer 817-USB. Calibrating only needs to be done once at the time of installation.
The display is calibrated in the units specified by the customer at the time of installation. Most commonly in Canada is liters (L) and cubic meters (m3).
Most common in the United States is barrels (bbl) and US gallons (gal)
The display is receiving the wrong number of bits from the sender bar.
Make sure both the display and sender bar are in the same inch mode.
Sometimes low battery in the display or the sender bar can cause this to happen.
This means no light (no L) is being received from the sender bar.

No. The communication protocol used between our senders and displays is proprietary. To control accuracy and functionality of our SeeLeveL ™ system the senders cannot be used in part with any other RV monitoring system.
No. The sender panels are sprayed with a protective coating for some protection.
On installations where the holding tank is exposed to under-chassis road spray and flying rocks etc., we recommend the use of rubberized undercoating.
Recommended brands:
3M 03584 Professional Grade Rubberized Undercoating.
Gravel Guard Rocker Guard Coating By Dominion Sure Seal
No. SeeLeveL ™ senders are not compatible with metal holding tanks. Will work on most plastic or poly holding tanks that contain water-soluble products.
No. Our SeeLevel I displays used a specific sensor that is no longer available. You would need to buy a new SeeLevel II system if any of the components of the SeeLevel I are no longer working.
The model and serial number can be found on the back of the display, under or beside the barcode.
No. The models that have the LPG readout feature can connect to your LPG tanks already equipped with an existing sensor.
Yes. The standard senders may be swapped out for the other available sender sizes.

No. The display is self-calibrated.
Yes. You can add a display in both inside your RV and in the service bay next to your tanks. This is helpful when you want to monitor the level while filling and emptying. Refer to the Wiring Diagram for two displays.
“Sht” is displayed when the signal line is shorted to ground.
“StA” appears when the display is programmed for one sender panel but dual sender panels are connected to that tank.
“OPn” stands for open circuit, meaning the display is not communicating with the sender panel. It is most likely from an open connection or damaged sender panel.
